Technical Field

[0001] The invention relates to the technical field of machine tool tool changing, in particular to a machine tool tool changing structure. Background Art

[0002] A lathe is a machine tool that mainly uses a turning tool to turn a rotating workpiece. Drills, reamer, reamers, taps, dies and knurling tools can also be used on a lathe for corresponding processing. When facing the same workpiece, different turning tools are sometimes needed to process it, and at this time, tool change is needed.

[0003] Existing machine tool tool changing usually adopts automatic tool changing technology, which uses the rotating shaft located in the center to change the tools on both sides. However, when the rotating shaft rotates to drive the changing rod to rotate, since there is no fixed clamping device at the front end of the changing rod, when changing the tool, even if the changing rod touches the tool, the tool change may not be completed smoothly, which greatly increases the workpiece processing time and causes delays in the construction period. Therefore, it is urgent to design a tool changing structure for machine tools to solve the above problems. Summary of the invention

The new knife gear 23 is connected to a new knife rotating shaft 24 at one end away from the new knife fixing disk 22. The other end of the new knife rotating shaft 24 is connected to the inside of the machine tool structure 01 and extends to the motor rotating bearing to ensure that it can receive power. A new knife 25 is provided on a side of the new knife fixing disk 22 away from the new knife fixing cylinder 21, which plays a role of replacement.

[0027] Furthermore, the old knife structure 03 includes an old knife fixing cylinder 31, which plays a role of fixed support. The new knife fixing cylinder 21 is connected to the old knife fixing disk 32 at one end away from the machine tool structure 01. The old knife fixing disk 32 is provided with an old knife gear 33 on one side close to the old knife fixing cylinder 31, which plays a role of transmitting power. The old knife gear 33 is connected to the old knife rotating shaft 34 at one end away from the old knife fixing disk 32. The other end of the old knife rotating shaft 34 is connected to the inside of the machine tool structure 01 and extends to the motor rotating bearing to ensure that it can receive power. The old knife fixing disk 32 is provided with an old knife 35 on one side away from the old knife fixing cylinder 31, which plays a role of cutting and processing. The positioning pin 36 passes through the old knife fixing disk 32 to rotate the old knife 35.

[0028] Furthermore, a plurality of motors are installed inside the machine tool structure 01 to provide power. The new tool fixing cylinder 21 is rotationally connected with the new tool fixing disk 22 to ensure that the new tool fixing disk 22 can rotate normally and rotate the required tool to the specified position.

The changing rod 42 and the rotating pin 43 are rotatably connected to ensure that the clamping plate 44 can rotate normally to clamp and release the tool.

[0031] Working principle: When in use, the motor inside the machine tool structure 01 drives the new tool rotating shaft 24 and the old tool rotating shaft 34 to rotate, and the rotation of the new tool rotating shaft 24 and the old tool rotating shaft 34 drives the rotation of the new tool gear 23 and the old tool gear 33, and the rotation of the new tool gear 23 and the old tool gear 33 drives the rotation of the new tool fixing plate 22 and the old tool fixing plate 32 to rotate the tool to be replaced to the specified position, and the old tool 35 is placed in a vertical state through the positioning pin 36, and then the motor drives the rotating shaft 41 to rotate The replacement rod 42 is rotated, and the corresponding part of the replacement tool 25 is placed on the outer wall of the tool to be replaced. The rotating pin 43 is rotated to fit the clamping plate 44 on the outer wall of the tool. After clamping the tool, the replacement rod 42 moves downward to take out the tool. The rotating shaft 41 rotates again to allow the two ends of the replacement rod 42 to interchange positions. The replacement rod 42 moves upward to install the tool. The new tool 25 is placed in a horizontal state through the positioning pin 36. Then the rotating pin 43 is rotated again to allow the clamping plate 44 to move away from the tool. The rotating shaft 41 rotates in the opposite direction to return to the original position to complete the tool replacement operation. The above is the entire working principle of the present invention.
